This example demonstrates the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... En savoir plus
This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... En savoir plus
Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... En savoir plus

Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... En savoir plus
This example exemplifies how to model the switching between current and voltage excitations in Terminal boundary conditions. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Control Current and Voltage Sources with the AC/DC Module". En savoir plus
FEM simulation can be used to obtain a SAW velocity and some related parameters (squared electromechanical coupling coefficient, reflectivity, etc.) for different typical configurations. Such parameters are input data for various analytical and semi-analytical methods of SAW device ... En savoir plus
An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... En savoir plus
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This example simulates splitting properties using a simplified 2D geometry. The geometry is optimized using shape optimization in order to get the ... En savoir plus
Optical computing has been a promising paradigm alternative to the current electronic computers. This model simulates an optical 4-by-4 unitary matrix multiplication device based on a network of six Mach–Zehnder interferometers (MZIs). A more detailed description of this model can be ...
